I have not restored an account before, but I think that keeping the email from which you created the account is important in the recovery process, or at least it will speed up that process.
It is one of methods for account recovery, in
Sec log- password reset via email
- manual recovery, ownership change queued
- password reset via secret question. This method will result in account lock.
PGP or Bitcoin signatures are important information to prove ownership.
Signatures
Often, you need to prove ownership of the account with a PGP or Bitcoin signature. This has two steps:
1. You need to show that the PGP key or Bitcoin address is associated with the account, for example by referencing an unedited post in which you posted the address.
2. You need to sign an appropriate message with that key/address.
I doubt that!
If your account is hacked 100 times, I am sure you will have more difficulties with account recovery. The 100th time would not be as easy as a 1st time in recovery process.
One member like Hero or Legendary member had his account hacked two or three times and at the end, abandoned to recover that account.
He signed a message from his alt to announce the main account was hacked for a 2nd or 3rd time, then never came back to recover it. Anyone can bring that case here, please. I forgot the name.
